All you need to do is buy a standard ATX power supply and snip the -5v wire from it. Not too difficult. If you are paranoid, just get an ATX cord extender and snip the -5v from it so you won't damage the original P/S.

-5v should be the white one, but doublecheck on the cords markings, and a multimeter if you have one

yes, whitlock is correct. I have done this at least twice myself. I probably have some photos sommewhere, but I think I found some online before my first try.

Now if anyone has the pinouts for a Quicksilver PS, I'd be interested in that!

Sorry for the incorrect info. I'm a 15 year old geek trying to break into the IT field, and I only do modding on the side and I do what I can. If I'm wrong, I'm wrong and lets just move on.
peace

Here are the Pinouts for most of the G4 PSUs:

http://www.outofspec.com/frankenmac/wire.shtml

Anything newer than a Blue & White is slightly trickier to convert from ATX, though the Yikes/Sawtooth is still fairly simple (Got this to work once). The GigE needs an extra 28V from somewhere which an ATX doesn't have. There are instructions on the site for this though.

thanx, good link, has what I need. the P4 connector is still a mystery, but I'm just trying to dump more current onto the 3.3v section to see if I can power up a Radeon 9700 (appple OEM) in a Quicksilver.

The small package on a B&W which contains the power and reset/nmi switches appears to output ~28v from a standard molex input -- I wonder if that could be used to drive the 28v on a digitalaudio and up MB? I'd wonder if it could generate enough current for the ADC, but other than that...

Is the P4 connector an ATX2? I think they're 24 pin. Shouldn't be too hard to find the pinouts for those.

As for the -28V from the B&W front panel, sounds interesting. Are you sure about that? I think the front panels on the Sawtooth are pretty much the same as those. I guess the 28V just switches on the PSU in the older towers and then they moved it to the PSU to cover the ADC connectors which were first shipped on cards with the GigE.

Where is the output for the 28 from the front panel? Don't have one handy to look at...

I'll have to put the meter back on one to be sure, perhaps it was 18v, it runs out through a two pin jumper back to the MB, and the over to the firewire adapter it looks like.

The P4 is a 4 pin connector from the Quicksilver PS to the MB, looks like it suppies 12v (x2) and at least one set provides extra power to the cpu board.

Anyone know which of the 3.3v lines services the AGP bus? smile
